I am currently working on an ASUS Q501L laptop for a client and I'm at a loss.

So this unit came in with the title issue. Any time the unit is utilizing (or trying to utilize) the network, the screen will shut off if it so much as shakes. You have to press the power button to put it to sleep and press it again to bring it back and it works again. At the lock screen, no issues. Move the screen as much as you want. As soon as you exit the lock screen to the desktop and a browser is open in the background, it shuts off again. Lock screen - fine. Exit lock screen - issue persists.

If you are not connected to the internet, and have no browsing tabs open, there is no issues. You can move the screen all you want and it stays on. The second I open Internet Explorer or any other browser/tool that uses the network (even if I'm not connected to the internet), the screen will shut off with the tiniest movement.

I found some malware and removed it with no success. Went through and verified all the drivers and services. Even went as far as doing a full system restore to no avail. That leads me to think it's a hardware issue but I've never heard of a hardware issue occurring dependent on what was currently open on the computer. I tried disconnecting the wireless card completely, and with no network connections, it worked. Then I opened Internet Explorer/Google Chrome and it died again, even though there was no network connection.

My colleagues and I are all at a complete loss so any help is appreciated.

Thanks!
 
Create a bootable Ubuntu flash drive, boot off it, and see if you encounter the same problem. That should establish pretty clearly if this is a hardware or software problem.

Try unplugging the antenna leads on the wifi card and see if you encounter the same problem. The antennas run alongside the LCD panel. It's possible that one is shorting out the display. If that is indeed the cause, since there are two antennas you can unplug the faulty one and run off just the one antenna. You really only need one antenna, having two just decreases the chances that the antenna will be in a bad orientation for a connection.
 


Unfortunately it will do it regardless of the nic card, dongle, etc. It will do it if I even so much as have a browser open. Thanks for the suggestion though, reedo! Even if I can't resolve the issue for the client, it's still a bizarre issue (to us anyways) that I'd like to figure out the cause, simply out of curiosity!
